Considerable development effort has been made in the past to meet the various requirements to create appropriate planer guidance. As part of this long-term development work, numerous Planer guides have been suggested, but most of them have not found their way into practice. In use Planer guides have proven their worth. However, they are generally only useful for certain extraction processes and plane types can be used.

The object of the invention is primarily to create a planer guide which, taking into account the of the Requirement made in practice /, such as above all high stability, easy assembly, easy access to the plow chain, etc., can be used in a variety of ways and in particular is also suitable for combined planing and cutting machine operation.

The planer guide according to the invention is characterized in that the hoods are used as a running surface for a Cutting machine have suitable head surface, the mining joint since ig by a towering over them, the upper guide of the Planes forming guide bar is limited, the thickness of which is smaller than the width of the head surface.

This configuration of the planer guide makes it possible at the Guide not just a planer, but, if desired, also guide a cutting machine with your The machine body engages over the conveyor like a portal in a known manner and on the opposite side the offset side profile of the conveyor or on a here arranged guide rail is supported and guided. The guiding of the cutting machine on the working face side On the top surface of the planer guide it enables the heavy weight of the cutting machine to be placed directly over the planer guide to put down on the lying. In addition, the

Construction and portal width of the cutting machine can be increased, what is advantageous with regard to the trouble-free conveyance of debris in the face conveyor. At the same time, the inventive Planer guide can also be used without simultaneous cutting machine operation. To the overall width of the planer guide To keep within limits, it is recommended that the face facing the working face, over which the in the Hobelgasse lying pile must be lifted, relatively steep, if necessary. even to ask about banking law. the The planer guide according to the invention uses the guide strips arranged on the cover hoods as the upper guide and as Underpass those connected to the sliding spacers Web strips, which are each gripped hook-like by the planer body in a known manner.

In a preferred embodiment, the arrangement is made so that the said lying rail, as known, of the The lower chain channel is formed on the underside delimiting leg of an angle rail, the towering of which Leg is connected to the mining face side with the conveyor. The top surfaces of the hoods can overhang the protruding Reach over the legs of the angle rail towards the conveyor and support yourself on it. With these structural Measures is a sufficiently wide running surface for the cutting machine and at the same time a reliable support of the hoods in the vicinity of their parts facing the conveyor side profile on the mining face side.

The invention also includes a planer guide in which the horizontal rail is made up in a known manner There are sections extending over the entire length of the trough section of the conveyor and with the sliding spacers Located below the hoods, the underpass of the planer forming web strips are connected, which are also over the entire length of the trough section of the conveyor

stretch. According to the invention, several foldable and independently of one another are in this case on one channel section length Arranged in the closed position fixable cover hoods. So while for the lying rail and the one with the sliding spacers connected web bar shots are used, the length of which is approximately the length of the trough length of the chain scraper conveyor corresponds, relatively short hoods are provided in this embodiment, the length of which is only one Corresponds to a fraction of the length of the gutter section. Such covers can be easily installed and removed handle and due to their comparatively low weight in the opening and without any particular difficulties Fold closed position. The one with the sliding spacers connected web strip here has a hinge pocket or the like expediently between their ends. on into which the joint parts at the ends of two adjacent covers.

The planer guide according to the invention is preferably designed so that, as is known, on each length of the guide and. Channel section at least two at a distance from each other arranged sliding spacers and at least one cover are provided, which or the like by means of plug-in hinges. are stored foldable and removable. With this configuration of the planer guide, there is the possibility of using the cover hoods if necessary at least on part of the length of the planer guide completely omit, so that here the returning upper run of the plow chain is exposed at the top. These Measure can be particularly useful in the strut area, where the plow chain is deflected from its normal Chain course must be guided on the plow chain wheel and therefore the wear caused by the plow chain in the planer guide is particularly large. To use the planer guide according to the invention even with the covers removed to be able to, it is advisable to go into the space between

However, the accessibility of the lower chain channel remains due to the detachable arrangement of the intermediate pieces obtain. Appropriately sized sliding spacers are expediently used as intermediate pieces. Particularly An arrangement is advantageous in which the spaced-apart sliding spacers through a continuous web strip are connected over the length of the guide or gutter section, and that too Intermediate formed as a Gleitdi punching piece !? If necessary, tuck into the space behind the bridges. steerable is.

In all of the aforementioned embodiments of the planer guide according to the invention, it is advisable to arrange the arrangement in this way meet that the working joint-side surfaces of the hoods and the web strips connected to the slide spacers lie in a common plane, which is expediently inclined only slightly with respect to the banking plane is. The end faces of the web strips and the cover hoods facing the working joint thus form one steep, closed and level surface. At this Execution, the overall width of the planer guide can be kept relatively small.

It is also advantageous if the mentioned hinges of the cover hoods are at the level of the sliding spacers. The straight or steep legs of the covers are given a relatively short length, which reduces the weight of the hoods will.

Pig. 7 shows in cross section a further embodiment of a planer guide according to the invention;

8 shows a partial perspective view of a planer guide according to the invention without a built-on guide Covers.

The planer guide shown in Figs. 1 to 5 is, as is known, built on the working face side of a chain conveyor, whose run of gutter consists in a conventional manner of individual gutter sections 10, of which in the drawing essentially only the side profiles 11 on the working face can be seen. Which is generally about the The planing guide, which extends over the entire length of the channel strand of the chain scraper conveyor, is also constructed in sections. It is used for the forced guidance of a swordless plane, which is not shown.

The planer guide consists of angle rails 12 and sliding spacers 13 »Web strips 14 and cover hoods 15. The angle rails 12, the length of which is approximately equal to the length of the individual trough sections 10 of the chain scraper conveyor have an upstanding leg 16 and a self on the lying supporting leg 17, which forms a slide for the planer body. The leg 17 is slightly inclined in relation to the lying plane (Fig. 4). It can be used in a known manner as a cut limit for the Serve planes. In this case he has such a length that he is about the size of the cutting specification of the plane The plane body protrudes towards the mining joint. On the other hand, the leg 17 can also have a shorter length, if its function as a section limiter is waived. The attachment of the angle rails 12 to the working face side Side profiles 11 of the trough sections 10 of the chain scraper conveyor are made in a known manner by means

Screw bolts 18 (Fig. 5), the bolt heads of which are supported in pockets by fitting parts 19, the outside are attached to the side profiles 11 e.g. by welding, the legs 17 of the angle rails 12 are slightly below the lower flanges 20 of the side profiles 11; as a result, they form the support of the chain conveyor on the working face side.

In a known manner, two sliding spacers 13, the length of which is smaller, are assigned to each channel and guide section is than half the length of the channel section, so that a sufficiently large dimensioned between the two sliding distance pieces 13 Gap 22 (Fig. 8) is present, over which the lower lying below the sliding spacers 13 Chain channel 23 is accessible from above. The sliding spacers 13 are by means of horizontal bolts 21 attached, which horizontal bolt holes of the sliding spacers and the upstanding legs 16 of the angle rails 12 through. The screw bolts 21 are supported with their bolt heads (not shown) on bracket holders the side profiles 11 or on corresponding fitting parts that are part of the fitting parts 19. These arrangements are known and are therefore not specifically shown in the drawing. The spacers 13 instruct their widened surfaces facing the working face pockets 24 which are screwed onto the bolt ends Pick up nuts 25.

The two sliding spacers 13 of each guide section are connected to one another via the web strips 14, whose length corresponds to the length of the gutter section. From the level of the sliding spacers 13 protruding downward web strips 14 can with the associated sliding spacers 13 be integrally connected. But they can also consist of special parts that are linked to the sliding distance

pieces 13 by screwing, welding or the like. tied together will. The web strips 14 form the lying or underpass of the planer, which in a known manner with guide arms or the like. is provided, which has a slot 26 between the lower edge of the web strips 14 and the horizontal rails 17 engages and the web strips 14 engages around a hook. At the border in the lower chain channel 23 Parts of the guide arms are connected to the traction strand of the endless plow chain, which pulls the plow along the working face. The upper run of the plow chain runs in an upper chain channel 27. The chain channels 23 lying one above the other and 27 are separated from each other by the sliding spacers 13.

Two cover hoods 15 are arranged on each channel section length, the length of which is accordingly approximately equal to half the length of the gutter section. The hoods 15 have a relatively wide, flat top surface 28, the working face side is limited by a towering guide bar 29, the width or wall thickness is considerably smaller than that Width of the top surface 28. The guide strip 29 forms the Upper guide of the planer, parts of the planer body grip it like a hook

The covers 15 are out of their closed position against the The working face can be folded down, as shown in FIGS. 1 and 4 at 15 '. In the closed position are the mining joint facing end faces 30 of the hoods 15 in a common plane with the end faces of the web strips 14, so that a practically continuous, not kinked surface from the upper edge of the guide strips 29 to the lower edge the web strips 14 is formed. This face is only weak to the bank right, e.g. by 10 to 20 °, inclined, which results in a relatively small overall width of the planer guide. The roughly angled cover

ben point down on their steep legs protruding fork-shaped joint pieces 31 and 32, of which one joint piece 31 at one end of the cover and the other joint piece 32 is arranged set back with respect to the other end of the cover hood. The other equally designed joint pieces 31 grip around with them Joint forks horizontal joint pins 33 (FIG. 4), which are set back in relation to the end face 30 in joint pockets 34 of the web strips 14 or the widened head surfaces of the spacers 13 are attached. The fork-shaped joint pieces 31, 32 point at their opposite the end face 30 recessed fork parts have a circularly arched outer contour 35. The inner surfaces 36 of the hinge pockets are correspondingly curved like a bearing shell, with wall parts 37 overlapping the fork parts upwards. This ensures that the hoods 15 in their closed position against lifting upwards from the Hinge pins 33 are locked by the wall parts 37.

From Fig. 1 it can be seen that the fork-shaped joint parts 31 at the ends of two adjacent cover hoods 15 each enclose in a common hinge pocket 34 and encompass a common hinge pin 33. These joint pockets 34 accordingly have a double width. The other joint parts 32 of the hoods 15 grasp each into its own hinge pocket 34, which is set back with respect to the end of the associated sliding spacer piece 13. In addition, it can be seen from Fig. 1 that the hinge pockets 34 in the plane of the screw bolts 21 and accordingly in the Level of the sliding spacers 13 lie.

In the closed position, the hoods 15 are fixed by means of short screws 38 (Fig «4), the nuts of which 39 bearing thread ends are sunk in recesses 40 of the head surfaces 28 of the hoods. At the upper end

that of the upstanding legs 16 of the angle rails 12 are Bearing pieces 41 attached, which consist of continuous strips or short profile pieces, which laterally have open pockets 42 for receiving the bolt heads of the screw bolts 38. To the covers 15 to solve and, as indicated by dash-dotted lines in Fig. 4, fold down in the direction of the working face, only need the nuts 39 to be turned off. When the cover 15 is folded down, the screw bolts can then be released take it out of the pockets 42 at the top. In the folded-down position, the hoods 15 can with their fork-shaped Joint pieces 31 »32 are lifted out of the joint pockets 34. The cover hoods are supported in the closed position with the underside of their web forming the head surface 40 on the bearing pieces 51 and thus on the protruding Legs 16 of the angle rails 12. The legs of the cover hoods provided with the head surfaces 40 have a such a width that they over the upstanding legs 16 of the angle rails 12 to the conveyor 10 up to about project to its side profile 11 on the side of the mine face. In this way a wide top surface 40 is obtained, which are also used as a running surface for a cutting machine moving portal-like over the conveyor can. The guide part of the plane which engages around the guide bar 29 like a hook has a width such that it occupies only a smaller part of the width of the head surface 40, so that there is sufficient space for on the head surface the support and guidance of the cutting machine remains.

As shown in particular in FIGS. 1 and 2, each second cover 15 has one at each of its two ends strip-like gap cover 43 on the upper half The contour of the chain channel 27 follows and ends in a straight leg towards the conveyor. The ones in between Cover hoods 15 are each with at both ends

GW 8016

■ 9.0 '

a corresponding pocket for engaging the gap cover 43 is provided. This way it becomes a reliable one Covering the gaps between the successive cover hoods and at the same time a mutual locking the covers reached. It can be seen that those hoods that protrude at both ends Have gap covers 43, can only be folded down against the working joint if the two beforehand neighboring hoods, which with the pockets 44 or the like. are provided, have been folded down.

The individual sections of the planer guide are via toggle bolt connections tensile strength, but connected slightly vertically and horizontally so that they can be bent against each other, whereby these toggle bolt connections absorb the full operating forces and, if necessary. the gutter weft connections can replace. As shown above all in FIG. 3, the sliding spacers 13 or those connected to them have Web strips 14 at the level of the center plane of the sliding spacers 13 on the ends of bolt pockets 45, which lead to the working joint are open and into which a known, in outline approximately H-shaped toggle bolt 46 can be inserted, the at its one widened head end an axial locking pin 47 which engages behind a wall surface of the pocket 45. On the other bolt head, projections 48 are formed in a known manner, which are also wall surfaces behind so that the toggle bolt 46 is secured in the pockets against falling out to the side. To a To prevent axial displacement of the toggle bolt 46 is a locking element consisting of a locking plate 49 is provided, which is fixed by means of a screw 50. The fuse element 49 prevents a axial displacement of the bolt within the bolt pockets 45. To loosen the toggle bolt 46, first the securing element 49 removed, whereupon the toggle

bolt 46 in the bolt pockets 45 so far (in Fig. 3 to the left) can be moved that the parts 47, 48 from the locking engagement arrive and the toggle bolt 46 can be removed from the side of the pockets 45.

T-bolt connections of the aforementioned type are known per se. It is particularly important here that the toggle bolt connection is arranged on the outside of the planer guide facing the working face. In addition, there is the bolt connection in the plane of the sliding spacers and thus also in a common plane with the connecting screws 21 and the hinge pockets 34 of the hood hinges. To at To create space for the toggle bolt connections at the ends of the guide sections, the joint parts 32 are on the one end of the hoods set back in the manner described.

The embodiment of FIG. 6 differs from that of FIGS. 1 to 5 essentially only in that instead of the short connecting screws 38 for the locking of the hoods 15 long screw bolts 51 are used, which horizontal holes of the hoods 15 and the upstanding legs 16 of the angle rails 12 through.

The planing guides described above are preferred intended for the combined planing and cutting machine operation. But they can also be used when there is no need to guide a cutting machine on the planer guide. On the other hand, the planer guide but can also be converted without great effort, e.g. by exchanging the cover hoods 15 for those of a different design will.

Fig. 7 shows a planer guide according to the invention, which in

their structure essentially that of FIGS. 1 to 5 corresponds, with only the hoods being changed. The covers 60 provided here do not have any serving as a running and guide surface for a cutting machine Surface on. They are provided with guide strips 61 which are arranged on the conveyor-side end of the cover hoods are. These guide strips 61 form the upper guide of the plane, which in the process engages around the guide strip 61 in the shape of a hook.

If desired, the planer guide according to the invention can also, at least over parts of its length, without cover hoods can be used. Such an arrangement is shown in FIG. Each guide section of the planer guide includes an angle rail 12, which extends over the entire length of the gutter section, and also a web strip of the same length 14 and two sliding spacers 13 »with which the continuous Web strip 14 is connected in one piece or by means of a screw or welded connection. As the covers missing, the upper chain guide is open so that the upper chain run runs freely while the lower run the endless plow chain is guided in the lower chain channel. To the lower chain channel 23 upwards close, in the space 22 between the two sliding spacers 13 is also made of sliding spacers formed intermediate piece 13 'is used, which by means of screw bolts, the bolt holes 62 grasp through, is fixed in a releasable manner. So that the lower chain channel 23 remains accessible, the connection is made in such a way that that the intermediate piece 13 'can easily be removed if necessary.
